Description Jeremy Katz 2000-08-07 02:05:43 EDT
Anaconda still isn't quite doing the right thing in the GUI install with
the Neomagic NM2160 which is in at least some of the Vaio 505 subnotes. 
During the install process, it detects as having only 256k of ram as
opposed to 2.5 megs -- changed to 2 megs.  Default X server pointed to is
the XFree 3.3.6 server, but the 4.x server has worked pretty well for me
throughout the beta thus far, and it's config file works right out of the
installer.  The 3.3.6 config file isn't in such good shape :(  The best
resolution of this imo is to point to the XFree4 server by default, but if
there have been some problems with neomagic chips on XFree 4, the following
probably need to be looked at

/etc/X11/XF86Config is created with a DefaultColorDepth of 32bpp, which the
amount of ram present can't ahndle at the highest resolution of 800x600. 
After changing the default depth to 16bpp, still only 640x480 is supported
because the ranges given when selecting Generic 800x600 LCD panel don't
encompass any of the 800x600 modelines.  Simply changing the VertRefresh to
be within the range of 60-65 instead of only 60 takes care of this (I've
seen this one in the past on mine and other laptops and this fix seems to
fix it across the board)

Even if a 4.0 server is used by default with the NM, I still think the
default 800x600 LCD panel modes for 3.3.6 are a little wacky and could hit
people using other chipsets that hit the XFree 3.3.6 path.

This defect is considered MUST-FIX for Winston Gold-release
Comment 2 Bill Nottingham 2000-08-15 22:21:12 EDT
Is this improved any in RC1?
Comment 3 Jeremy Katz 2000-08-16 11:13:30 EDT
To be honest, I can't say -- RC1 came out right before I left for Linux World
Expo and as the box is the only machine I have to check my email with while I'm
out here and I've got no CD drive (forgot the CDs anyway.. *doh*) and the
network connection to the show is saturated, I'm a little reluctant to try and
test this until I get back to Raleigh on Friday...  but, I will test it once I
get back to Raleigh Friday night
Comment 4 Jeremy Katz 2000-08-19 11:08:02 EDT
Default modes allowed for 800x600 LCD panel are a lot better in RC1. 
Unfortunately, anaconda is  still putting 'DefaultColorDepth 32' in the 3.3.6
config file and using 3.3.6 by default which just doesn't work at all with the
amount of RAM the chip has
Comment 5 Trond Eivind Glomsrxd 2000-08-19 15:22:20 EDT
Note that "256 kB" of detected memory means that detection didn't succeed.
Comment 6 Trond Eivind Glomsrxd 2000-08-19 15:35:07 EDT
We're switching to XFree4 for neomagic now...
Comment 7 Jeremy Katz 2000-08-22 00:52:21 EDT
Looks good in RC2.  My laptop now actually installs and starts X without my
doing any tweaking of config files post-install which is nice :)
